BUNG.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed April 28, 1908. Seria1 No. 429,779.

To all whom tt may concern:

Be it known that I, WALTER I-IENRY GERALD, of Prescott, in the county of Grenville, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Bungs, of which the following is a specication.

My invention relates to improvements in bungs and the objects of my invention are to provide means enabling the automatic adjustment of the bung during tightening and clamping of the same, whereby it may adjust itself to accurately fit the bung hole, and so effect a tight closure.

The construction of the invention is described in detail, more fully in the accompanying specifications and drawings.

In the drawings,-Figure 1 is a sectional view through the bung. Fig. 2 is a perspective view of the bung carrying member. Fig. 3 is a perspective view of the bung. Fig.` 4 is a perspective view of the bushing. Fig. 5 is a section through an alternative form of the invention. Fig. 6 is a sectional view through another alternative form.

In the drawings like letters and figures of reference indicate corresponding parts 'in each figure.

Referring first to the form illustrated in Figs. 1 to 4, A represents the stave of a barrel or other receptacle having a bung hole 10 therein. B represents the bushing, preferably of metal, which extends around the interior thereof and which is retained in position by the screw-threading 11. formed on the exterior thereof. To prevent turning movement of the bushing, lugs 12 and 13 maybe provided adapted to extend on the inside of the arrel stave and be retained in position by screws 14 and 15 extending through apertures in the lugs. In this form of the invention, the interior of the bushingis formed with a valve seat 16, on which the bung proper C is adapted to seat, this bung being preferably constructed of wood, or like material. The bung is carried, and adapted to be clamped, by a rotatable member D, the connection between the two being in the form of a tongue and groove joint in which a dove-tailed projecting flange 17 is formed on the bung extending into a dove-tailed slot 18 at the bottom of the rotatable member. This rotatable member is externally screw-threaded and en aged with an interiorly screwthreade surface 19 on the bushing, and has also formed thereon a recess 2() having a transverse rib 21 for convenience in turning. When it is desired to withdraw the liquor from the barrel or receptacle, the rotatable member is unscrewed and the bung is withdrawn. To close the bung hole, the screwthreaded member is screwed home, which will tightly bind the bung in closed position. The bung being only loosely held by the rotatable member may adjust itself on the valve seat 16 in order that the tightest joint possible may be made between the two. It will be seen that this construction, in reality, provides an automatically adjustable bung for, as the bung is being screwed home, it can adjust itself with respect to the carrying member, in order to lit accurately the bung hole or valve seat formed thereon.

In the form shown in Fig. 5, the valve seat 22is formed on the inner side of thebung hole, while the bushing E extends only half way through the staves and is inserted from the outside, and it is provided with a flange 23 extending over the outer surface-of the stave. In this form, the dove tailed flange 24 is formed on the rotatable member, while the dove tailed slot 25 is formed in the bung.

The form shown in Fig. 6 is the same as that shown in Fig. 5, with the exception that the flange 23 is omitted, and the top of the bushing F is left Hush with the outer surface of the barrel stave.

It may also be observed that in the forms shown in Figs. 5 and 6, no metal at all appears in the inside of the barrel or bung.

As many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the spirit or scope thereof, it is intended that all mattei' contained in these specifications and drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language of the following claims is intended to cover such generic and specific features of the invention herein described which, as a matter of language might be said to be included thereby.

'What I claim my invention is:

1. The combination with a receptacle having a bung hole in the side thereof, of a bushing extending around the bung hole, a bung carrying member, an automatically adjustable bung supported therefrom, adapted to adjust itself during tightening to lit the bung hole and clamping means for the bung carrying member.

2. The combination With the receptacle having a bung hole therein, a bushing eX- tending around the bung hole, abung Carrying member and an automatically adjustable bung having a tongue and groove connection Withthe bung carrying member and adapted to adjust itself to ft the bung hole, as the 10 bung carrying member is tightened, and

clamping means for the bung carrying member.

3. The combination With the receptacle having a bung hole therein, of a bushing eX- tending around the bung hole and bung car- 15 rying member having a screw-threaded engagement With the bushing, and an automatically adjustable bung supported from the bung carrying member and adapted to adjust itself automatically to ft the bung 20 lhole as the bung carrying nmember is screwed Lome.

In Witness whereof l have hereunto set my hand in the presence of tWo Witnesses.
